Quench modelling of Al-7Si-Mg casting alloys
No full textQuench factor analysis was applied to A356 and A357 aluminium casting alloys in order to model time-temperature-yield strength curves, to predict T6 yield strengths as a function of continuous cooling quench rate and to examine quench sensitivity. The predicted T6 yield strengths for given quench curves were typically within +/- 10 MPa of experimentally measured yield strengths. It was found that A356 is more quench sensitive than A357 at high quench rates, whereas A357 is more sensitive at low quench rates. This is explained in terms of silicon clustering, which alters the matrix Mg/Si ratio and subsequent precipitation events. These observations were confirmed by differential scanning calorimetry
